Title: Double balanced modulating systems for carrier wave signalling
IPC: H03C1/58
Filed: 1939-01-13
Abstract: 523,897. Modulating systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 13, 1939, No. 1218. Convention date, March 3, 1938. [Class 40 (v)] In a double balanced modulator or demodulator, the use of transformers for the input and output frequencies is avoided by an arrangement in which each arm of a primary bridge consists of a secondary bridge of rectifiers with the carrier frequency applied to one diagonal. The main bridge A, B, C, D, has signal applied to diagonal BD and the load connected to diagonal AC. Each arm 1, 2, 3, 4, consists of four rectifiers, such as 11, 12, 13, 14, connected in a bridge with carrier frequency applied to the free diagonal from one of the secondary windings on the multi-winding carrier-frequency transformer T. In order to secure more identical bridge-arms, each rectifier may be composed of two or more rectifiers so that accidental inequalities in the rectifier characteristics tend to cancel out. The rectifier elements may be any non-linear devices and may be controlled in any known manner, such as for instance by means of grids. U.S.A. Specification 2,025,158 is referred to.

Title: Improved manufacture of condensation products of aldehydes with ketones
IPC: C07C45/72
Filed: 1927-01-17
Abstract: 264,830. I. G. Farbenindustrie Akt.- Ges. Jan. 19, 1926, [Convention date]. Ketols; potassium diacetone alcoholate; diacetone alcohol; hydracetylacetone; hexanol-4- one-2; octanol-5-one-3; crotylidene acetone; cinnamylidene acetone; ethylideneacetophenone; oethylidenecyclohexanone.-The condensation of an aldehyde with a ketone is performed in the absence of water and with the use as condensing agent of an alkali compound of a 1 : 3 ketol. The condensing agent may be produced by treating with anhydrous solid alkali in the cold the ketone which is to be condensed, whereafter the aldehyde is added gradually to the solution of condensing agent in excess of ketone. The aldehydes may be saturated or unsaturated aliphatic or aryl-substituted aldehydes, and the ketones may be saturated or unsaturated aliphatic or aliphatic ring ketones, or aralkyl ketones. In one example, acetone is treated at 5‹ C. with powdered caustic potash, whereby the potassium compound of diacetone alcohol is produced. The cooled solution is treated with acetaldehyde gradually and with stirring, whereafter carbon dioxide is passed in to precipitate potassium carbonate, and the excess of acetone is distilled off. The residue contains diacetone alcohol and hydracetylacetone. In other examples acetone is condensed with propionaldehyde, the product being hexanol-4-one-2, and methylethyl ketone is condensed with butyraldehyde, the product being octanol-5-one-3. Reference is made also to the condensation of crotonaldehyde and acetone to a ketol which subsequently loses water and forms crotylidene acetone, and to the preparation in similar fashion cf cinnamylidene acetone from cinnamic aldehyde and acetone, ethylidene acetophenone from acetaldehyde and acetophenone, and o-ethylidene cyclohexanone from acetaldehyde and cyclohexanone. The products are useful as perfumes or as intermediates in making perfumes.

Title: Process for the improvement of viscose textile materials by esterification
IPC: C08B3/00
Filed: 1941-02-04
Abstract: 546,657. Esterifying cellulosic textile materials; dyeing processes. COTOPA, Ltd., and TRENCH, J. KNIGHTS-. Feb. 4, 1941, No. 1462. [Classes 2 (ii) and 15 (ii)] Fibres, or fabrics of regenerated cellulose from viscose are treated with an aqueous alkali solution, then with an aqueous lower aliphatic acid, i.e. an acid up to and including butyric acid, of not less than 90 per cent strength, and then with an esterifying medium containing the lower aliphatic acid, its anhydride, and a heavy metal halide as catalyst. The treatment increases the weight of the materials, renders fabrics resistant to shrinking and creasing, improves the wet tensile strength, and imparts a linen-like finish. Esterification may result in the production of cellulose acetates of 20-62.5 per cent combined acetic acid. The materials may be dyed before or after the esterification. Specified dyes which are suitable for dyeing before the esterification are substantive dyes such as Chloramine Fast Orange W.S., Solar Yellow 2R, and Primuline after-treated with hypochlorite; developed colours such as Diazo Fast Scarlet BL# #- naphthol, Diazol Black SD# m-toluylene diamine ; vat dyes such as Sandothrene Yellow NGC, Durindone Pink FFS, Caledon Dark Blue 2RDS, and Indanthrene Brown BR; sulphur dyes such as Thional Black T. Mixed yarns or fabrics containing viscose and cotton fibres may be treated, and since cotton is more resistant to esterification, the viscose fibres may be made resistant to direct cotton dyes while the cotton still retains affinity for such dyes. Differential dyeing effects may thus be obtained. In an example, viscose yarn, fabric, or sliver, is treated with hot dilute caustic soda, washed, dried, treated with warm concentrated acetic acid, and centrifuged. The material is then treated with a solution containing acetic anhydride, acetic acid, and zinc chloride, ferric chloride, or other metal halide catalyst, for several hours until the material contains up to about 45 per cent. combined acetic acid. To obtain further esterification, the partially acetylated material may be treated in a fresh bath containing zinc chloride, benzol, acetic acid, and acetic anhydride. Toluene or xylene may be used instead of benzol. The Provisional Specification describes also the use of perchloric acid as catalyst for the esterification.
